[Solved]How to take default value of a?

https://code.sololearn.com/WqaOExkzq02X/?ref=app I want to take default value of a, and willing to input value of b in function. I don't want to change order. I tried many times. I think there should be a way, because I think it is necessary.

Use undefined instead of null.
